If you selected "Other scale" at the message box as shown in Fig. 110, you can enter other scale as
shown in Fig. 0. Keying in an analog value corresponding to the 4mA output (V in this case) in the
upper field (4mA setting) results in entering a corresponding value in the lower field (20mA setting)
automatically.
Fig.0
Entering any value in lower
field is not required. Enter
appropriate value in upper
filed, and the right value
will appear in lower field.
At this point, you can trim the analog output on the 1-5V scale.
Click on "OK" to begin the trim process. Couple the test instrument (reference voltmeter) across load
resistor R
L
.
⑨
A message box like the one shown in Fig. appears. Select either the 4mA trim or the 20mA trim.
Firstly the 20mA trim is described here, followed by the 20mA trim.
Key in the reading of the test instrument and click on
"
OK
"
button.
As the reading is transferred, the transmitter automatically adjusts the output to 4mA. Verify that the reading
of the measuring instrument connected registers V.
If it proves that readjustment is required, enter the ammeter reading at this message box and click on "OK"
.
⑩
To proceed to the 20mA trim, click on the 20mA at the message box like the one shown in. Fig.
and, similar to the 4mA trim procedure, trim the reading until the test instrument connected registers
V.
⑪
Clicking on "Cancel" button completes the analog output trim. A message box like the one shown in
Fig. 112 appear. Click on "OK" button.
